3.5. Programming Examples
The following programming examples are intended to facilitate the evaluation of various modem features and serve
as example command strings used in part or in combination to create the desired modem operation. Table 75
summarizes the modem function/feature and the associated hardware pins, AT commands, S-Registers, and U-
Registers. When a command string is created to enable a particular feature, Table 75 should be reviewed to make
sure all necessary pins, commands, and registers have been considered.
